IMPROVEMENTIN HARVESTERS.

Specifica-tion forming part of Letters Patent No. 22,824, dated February l, 1859.

To all whom it may concern.'

Be it known thatwe, SYLVESTER PERSONS l and ALFRED M. GONE, of Panama, inV the county of Chautauqua and State of New York, have invented new and useful Improvements in Grain and Grass llarvesters; and we do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to theletters of reference marked thereon.

Figure I is a perspective of the machine. Fig. Il is a plan of the same, the cap or upper partofthe cutter-frame being removed in order to show the chain cutter more distinctly. Fig. III is a bottom plan of the cutter-frame. Fig. IV is an elevation of several links of the cog-chain. Fig. V is a section through the line y, Fig. IV, and shows the form of the cuttertooth and themanner of fastening it to the chain. Y

Letters of likename and kind refer to like parts in each of the figures.

A is the driving-wheel; B, pinion; O, multiplying-wheel; D, lever. On the lower vend of this lever is a pinion, which meshes in with a pinion on the cutter-frame for the purpose of E, main frame; F and G, cutter-frame, F being the upperl part and Gr the lower part. These two parts, when put together, form a case or frame for the support and protection of the cutters.

Whatever may be the details of the construction of the cutter-frame, it must possess the two features of adjustability for reaping and vibration in the direction, so that the forward part, which slides upon the ground in mowing, will conform to the uneven surface of the ground. These two features are produced by swinging the cutter-frame upon theaxle L, (giving a preponderance of weight forward of the axle,) and making thetframe sufficiently wide, so that the forward partwhich sustains the guard-fingers, will slide upon the ground when mowing, while the rear part is curved sufficiently high to pass over the mown grass.

H and I are guard-lingers, made in two parts, H being the upper and I the lower half. The upper half of the guard is made` fast to the cappiece or upper part of the cutter-frame. The

lower part ofthe cutter-frame.l When the two d, friction-rollers to carry the cutter-chain around the corners; J J J, Fig. III, frictionrollers which support the cog-chain under the multiplying-wheel c, and which hold the chain in gear with the multiplying-wheel through all the variations caused by the vibrations of the cutter-frame; K, caster-wheel for supporting and carrying the outer end of the cutter-frame L, shaft or axle which connects the cutterframe to the mainframe ofthe machine. This should be so placed upon the cutter-frame as to give a preponderance of weight forward of the axle, so that the forward part of the frame,

to which the guard-fingers are connected, will bear upon the ground and conform to the unlevel surface thereof; M, journal-box. l

N is a segment on shaft L, and O is a segment on the end of lever D, by means of which the cutters are raised and lowered in an aro of a circle of which L is the center; P, Fig. II, caster-wheel for supporting the rear yend of the main frame; Q, cutter-chain. This chain is made in links, witl cogs thereon, and the links are fastened together by means of pins or rivets, as represented by the dotted lines r r, Fig. IV. A mortise is made through the link, and a tenon is `made on the base of the cutter-tooth, which fits the mortise in the link, as shown at s. A rivet passes through the link, and also through the tenon of the cutter-tooth, as shown at t, Fig. V, the shoulders of the tooth resting against the link, and thus the tooth is held rmly in its place. W, cutter-tooth.

The chain cutters are arranged upon the cutter-frame (the cutter-frame being constructed wide enough for the purpose) so that the cutters will rotate around an area sufficiently large to allow the cut grain to fall upon the platform upon the area and the cut grass to fall upon the ground within the areaencircled by the cutters. By this arrangement we are enabled to make the front part of the frame, which sup- 2. gasa-Q.

ports the guard-fm gers, so narrow and freethat the out grain or grass cannot lodge thereon,

and so that the cutters can free themselves and prevent clogging.

We contemplate using appropriate dividers at the outer and inner end of the cutter-frame, so that when the machine is used for cutting grain (a removable plait-form being also used) the grain will be guided onto the platform, and when the machine is used for cutting grass the platform can be removed and the out grass will fall Within the area inclosed by the cutters.

We claim- 1.`Arranging and operating the chain cutters upon an adjustable and vibrating cutterframe, in the manner and for the purposes substantially as described.

2. The arrangement of twoor more rollers, J J, relatively to the chain cutters, multiplying-Wheel c, and adjustable vibrating cutter- SYLVESTER PERSONS. ALFRED M. GONE.
